Bradley Paul Walker (born 25 April 1996) is an English professional footballer who plays as a defensive midfielder for EFL League Two club Tranmere Rovers.

[15] The 2014–15 season saw a loss of form for Walker and most of the Hartlepool team in general, with manager Colin Cooper and his successor Paul Murray both dismissed before Christmas.

[17] Walker then fell out of manager Ronnie Moore's first-team plans in the 2015–16 season and spent time on trial at Wolverhampton Wanderers; no move to Wolves transpired though he continued to be linked to the club as late as summer 2017.

[24] He turned down the offer of a new contract from newly appointed manager Craig Harrison following the club's relegation out of the Football League at the end of the season and was linked with moves to Wolverhampton Wanderers and Wigan Athletic.

[26] Walker signed a two-year deal to join Crewe Alexandra after the League Two club paid Hartlepool an undisclosed compensation package on 4 July 2017.

[29] His first season at the club was described as "mixed" as he started well but transitioned from central midfield to centre-back and ended the campaign finding gametime limited after struggling with injury problems.

[35] However, Crewe manager David Artell commented that if Wrexham wanted to keep Walker they would have to sign him permanently as he otherwise expected the player to return to Cheshire in January with "fire in his belly".

[39][40] The loan spell was ended early in March after he picked up a hamstring injury; he had made a total of 32 appearances for Wrexham, scoring 4 goals.

[41][42] Walker finally made his debut for Shrewsbury on 10 August, the second game of the 2019–20 season, coming on as a 79th-minute substitute during a 1–0 defeat at Milton Keynes Dons.

[45] After working hard on his fitness during England's first COVID-19 lockdown, he finally forced his way into the starting eleven following injuries to David Edwards and Sean Goss.

[49] On 2 June 2021, Walker agreed a two-year deal with League Two club Port Vale, becoming Darrell Clarke's first signing as manager.

[57] On 12 January 2023, Walker joined EFL League Two side Tranmere Rovers for an undisclosed fee, signing a two-and-a-half-year contract; manager Micky Mellon said that "for a while we've been looking for players of Brad's size and physicality in the midfield areas".

[62] In October 2024, Walker received a three-match ban for violent conduct following an incident in the 51st minute of Rovers' 3–1 defeat at previous club Crewe Alexandra.
